Network>ARP
ARP (Address Resolution Protocol) maps layer 3 (IP addresses) to layer 2 (physical or MAC addresses)
to enable communications between hosts residing on the same subnet. ARP is a broadcast protocol that
can create excessive amounts of network traffic on your network. To minimize the broadcast traffic, an
ARP cache is maintained to store and reuse previously learned ARP information.
It is sometimes necessary to flush the ARP cache if the IP address has changed for a device on the
network. Since the IP address is linked to a physical address, the IP address can change but still be
associated with the physical address in the ARP Cache. Flushing the ARP Cache allows new information
to be gathered and stored in the ARP Cache. Click Flush ARP Cache to clear the information.
To configure a specific length of time for the entry to time out, enter a value in minutes in the ARP Cache
entry time out (minutes) field.
